Chlorine Kills

Chlorine kills most bacteria such as E. coli in about a minute if it is maintained at proper disinfection levels (1–3 parts per million [ppm] free chlorine) and under ideal water conditions (pH at 7.5 or less; temperature at 77° F [25° C] or more) throughout the pool. However, a few germs are moderately (Giardia and Hepatitis A) to highly (Cryptosporidium) chlorine-tolerant.

Use a pool test kit to check levels and water quality. Just follow the instructions in the step-by-step guide that comes with your test kit for checking your pool water’s pH, total chlorine, total bromine, acid demand, and total alkalinity. The instructions are pretty straight forward and simple to follow.
